The introduction of 5G technology heralded a new era in wireless communications, promising unprecedented speed, capacity, and low latency. In this paper, we analysis the performance of 5G mobile communication in an urban macro environment. The performance is analyzed through computer simulation. The simulation work is performed by NYUSIMULINK simulator, a powerful tool for simulating radio wave propagation in complicated environmental contexts while taking into account multiple propagation models, antenna configurations, and channel characteristics. This study contributes greatly to the ongoing research on 5G deployment by giving an in-depth analysis of the deployment of 5G technology in urban macro scenarios at 30 GHz. Our findings provide insight into the performance traits of 5G networks in difficult urban areas, opening the door for future 5G deployment techniques that are more effective and efficient. Performances are based on antennas and research shows that more loss occurs on a directed channel than on an omnidirectional one. Our contribution is centered on a thorough examination of the variations in signal strength when using 30 GHz in urban macro contexts. The findings show that, even with its large capacity, running at 30 GHz necessitates careful network architecture in order to provide dependable performance in crowded urban environments.
